SPECIPICATIQN forming part of Letters Patent No. 307,883, dated November 11, 1884.

(No model.)

To all whom it may concern.-

Be it known that I, SAVILLION VAN OAMPEN, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented certain Improvements in Covers for Books and Method of Attaching Same, of which the following is a specification.

My invention relates to improvements in that class of books technically termed stitched books as distinguished from sewed books; and the objects of my improvements are, first, to provide a stiff cover for such books having a formed back and with means for attaching the sides thereto; and, second, to provide means for connecting the cover to the book and to give it the appcarance of the ordinary bindings.

In binding books by the ordinary process it is customary to secure a strong cord or a strip of tape or parchment to the back or'fold of the leaves during the process of sewing the signatures together, and which is still fur ther secured to the book by paste or glue. The two pieces to form the sides of the cover are secured to the cord or strips and the back piece is then fastened to the sides.

In edition work in cloth or'muslin'it is the usual practice to prepare cases or covers for the book consisting of stiff sides with a flexible back. These are connected by cementing the cord or strips to the sides of the cover.

The methods above described for attaching the covers are not practicable where books are stitched through and through with thread or wire for several reasons, principal among which is the difficulty of securing cords or strips to the back of such books, and the fact that a book stitched through and through will not open as freely as a sewed book.

My invention aims to produce a stiff cover that is adapted for use on stitched books that can be furnished to the binder at a trifling cost and in a manner ready for immediate adjustment on the book. A

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a perspective View of a book with my improved binding or cover. Fig. 2 is a similar view,

but showing only the back portion of the cover secured to the book. Fig. 3 is a like perspective view showing a modification of the fastener for securing the back of the cover on the book; and Figs. 4: and 5 are detail views in perspective of the outer strip for the cover and the back portion of the cover to inclose the back of the book, the flaps being removed.

My improved cover as a whole comprises three separate pieces, exclusive of the sidesnamely, a back part composed of stiff pasteboard molded or otherwise formed into a shape adapted to fit over the back edge of the book, and having tags to which the sides of the cover may be attached, a fastening-strip for securing this back onto the book, and an outer strip formed into shape to inelose the back and give to the cover the finished appearance of the best styles of binding.

Referring to Fig. 1, let a represent a book provided with one of my covers, of which bis one of the sides and 0 the formed strip inclos ing the back. In Fig. 2 the side I) and strip 0 are removed, and only the back (2 is shown attached to the book a. This back (I of the cover is composed of a piece of stiff pasteboard, pressed, molded, or otherwise formed up into the shape shown in Fig. 5, consisting of a flat back part, c, and sides 6 e, forming a case adapted to fit closely over the back edge of the book, as shown in Figs. 2 and 8. The sides of the back (I are designed to project over the sides of the book far enough to conceal the stitches which bind its leaves together and to form a well-defined edge or support on which the leaves of the book will readily open. On the sides 0 of this back are cemented flaps or tags f, made of cloth or other suitable material, to which the sides I) of the cover are attached by means of glue or paste.

9 g are narrow strips of metal which are passed through apertures formed in the body of the book and are clamped down on the back, as shown in Fig. 2. The sides 6' c of the back (I are cut away or recessed, as shown at h, so as to receive the strips g and enable them to be bent down firmly against the side and hold the back so securely in place on the book as to prevent any tendency to slip in either direction.

XVhen binding the book, the back (I is first secured to the back edge of the book by means of the clamping-strips g. The sides I) of the cover are then attached by paste or glue to the flaps or tags f, and finally the formed strip or enrelope c is applied by means of paste or other adhesive substance to the back (1, whereby a general outward appearance is given to the binding similar to that found in the best styles of books. preferably composed of a piece of stiff pasteboard formed by means of suitable dies or ma chinery into the shape shown in Fi g. 4:. hen this outer envelope or case is secured over the back (I, the back of the cover has a shape similar to the ordinary cloth bindings.

In Fig. 3 I have shown a modified construction of the clamping device for confining the back (1 to the book; In place of the fiat strip of metal shown in Fig. 2,1 employ a piece of wire, 3'. The holes in the book and the recesses in the sides of the back (I will of course be made to correspond with the size of the wire.

To secure the back (I to the book by means of the wire j,(see Fig. 3,) I first pass the wire through one of the perforations in the book, carry it diagonally across 011 the outside of the back (1, and then, passing it through the other perforation, bend the two ends down onto the back, as shown. This method of introducing the wire insures a firm attachment. Instead, however, of using a single wire,as here shown, I may employ short wires and merely pass them through the book and clamp the ends down on the back (1 in a manner similar to the bands or strips g.

WVhat I claim as new, and desire to secure by Letters Patent, is V 1. In a cover for stitched books, the combination, with a book, of aback piece composed The outer envelope or strip, 0, is

sisting of a back piece formed to inelose the back edge of the stitched book, having recesses in the side portions thereof, and having flaps for connecting the sides of the cover with metal strips passing through the book and around the back piece, as set forth.

8. The book-cover herein described, consisting ofa back piece formed to fit over the back edge of the book, and having its projecting sides cut away to receive one or more metal strips that are passed through the book, in combination with the side covers secured by flaps to said back piece, as set forth.

4:. The combination, with a stitched book, of a cover consisting of three separate and es sential partsthe back (I, secured to the body of the book by strips of metal or wire inserted through the two projecting parts or sides of the back and secured on the outsidc,the sides b, and the tags j", for connecting the sides to the back, substantially as set forth.

5. The combination, with a stitched book, of a stiff back piece secured to the body of the book by means of thin metal bands or by wires passed through the book and around the back of the cover, substantially as set forth.

6. The back (1, consisting of a piece of stiff pasteboard bent to project over or overlap the sides of the book far enough to cover the stitching, and havingv tags f, to which the sides 6 are secured, and adapted to be attached to the body of the book by strips of metal or wire, as set forth.

7. The combination, with the back d and sides I), of the strip c, for1ned, substantially as shown, to simulate the form of the backs of ordinarily-bound books, and adapted to conceal the metallic fasteners used to secure the cover to the book, as set forth.
